I feel like if they had evolved to where we are at they would just chill and all there tech would be centered around food and playtime. (Some tan parents would also be like “we got you this super expensive video game console and you’re playing with a stick??”). No wars or violence. Except during mating season when the males would rumble, probably in some relatively harmless ritual sport or something. Otherwise just peace and rolling down hills and looking around in wonder there in 'Tantopia.
